A plurality of spacers/adjuster slide blocks (3) are located at spaced apart locations between the conveyor side panels. The spacer/adjuster slide blocks have central apertures axially aligned therein. A  plurality of pairs of parallel oriented adjuster slides (4) are mounted for axial movement above and below the apertures of the spacer/adjuster slide blocks. The adjuster slide of each pair having gear teeth in linear alignment, thereby constituting racks. An adjuster gear (5) with gear key for each pair of slides is formed in a cylindrical orientation constituting a pinion mounted with an aperture aligned with the apertures of the spacer/adjuster slide blocks. A product guide rail (8) is located on each side of the path of travel above the conveyor chain and is coupled with respect to the upper ends of the adjustable rail support (7). Lastly, an adjustable drive rod (11) couples the adjuster gears for simultaneous rotation therewith.

Title: General scheme of using encodings in computations
Inventor: CHOW STANLEY T
IPC: G06F21/14
Filed: 2001-05-24
Abstract: This report is devoted to measuring the resistance of data encodings to reverse engineering. We introduce a measure of encoding resistance in an en-coded world as a measure of uncertainty: specifically, the number of possible or 'real' worlds which can correspond to the observable encoded world. An attacker observing only operations in encoded world and inputs to encoded world (i.e., all encoded input data) can not distinguish between any of 'real' worlds. Thus the larger the number of corresponding 'real' worlds, the more uncertainty and resistance the encoding has.      It is important to note that such measures characterize the resistance of encoding to an arbitrary attack which only uses information from the encoded world.      We present estimates of resistance of linear, residue and mixed encodings for addition and multiplication and find that maximal resistance is achieved for mixed encoding. We show that there exist more resistant schemes for performing multiplication in mixed encodings.      We estimate resistance of computation of arbitrary multivariate polyno-mials in mixed encoding and proposed several ways to increase the resistance of arbitrary computation in mixed encoding.

Title: Method and device for positioning teat cups on a milking animal
Inventor: NILSSON MATS
IPC: A01J5/017
Filed: 2000-01-13
Abstract: The present invention relates to a method for positioning animal related means, e.g. teat cups, of a milking animal, more specifically to a method to initialise an automatic positioning device to utilise a sequence of movements associated with said animal. The sequence of positioning movements is associated with a class to which the animal belongs among a plurality number of classes corresponding to the identity of said animal. The animal is beforehand assigned to a class based on its individual position of each teat. The different sequence of movements, adapted for different shapes of udders on the animal, may speed up the process for positioning the teat cups and thereby increase the through-put of animals in the system. The present invention also relates to a control device.
